Homestuck, as referenced above, is a webcomic also known as MS Paint Adventures. A lot of the Other Girls artists here are Homestuck fans. A lot of them link to their DeviantArt pages from their Tumblrs. It’s a certain young, female-heavy overlap of these three cultures.

Not overly fond of the slut shaming, but the parodies are funny nonetheless. There’s also a thing as “Fake girls vs. Precocious-pretending-to-be-the-most-unique-gift-out-there-when-you’re-stupid-tumblr-and-”nerdy”-girls”. Just pointing it out there :I
